Graphing Train Timetable

Before the introduction of computers one of the most complex mathematical tasks that had to be completed on a regular basis was the construction of train timetables. Railway schedulers typically used graphical construction techniques to chart the course of trains through a typical day. To see how timetable graphs could be used the article consider a mythical train line example. Preparing train timetables in this 'old fashioned' way allows us to see the important use that simple graphing can be put to.
